使用　FULL OUTER JOIN　报错信息为“SQL 命令未正确结束”

SQL语句如下：
select dttest as DTIME,(1 - intsucceed/inttimes)*100 as LRT,ifoutval/(1000*1000) as OUTFLUX from testrecord FULL OUTER JOIN snmp_val1 ON (testrecord.dttest=snmp_val1.dt)

报错信息为：
SQLWKS> select (1 - intsucceed/inttimes)*100 as LRT,ifoutval/(1000*1000) as OUTFLUX from testrecord FULL OUTER JOIN snmp_val1 ON testrecord.dttest=snmp_val1.dt
2>
select (1 - intsucceed/inttimes)*100 as LRT,ifoutval/(1000*1000) as OUTFLUX from testrecord FULL OUTER JOIN snmp_val1 ON testrecord.dttest=snmp_val1.dt
*
ORA-00933: SQL 命令未正确结束


请问错误在那里？
